ACT Lab Meets SURESTOP

ACT Lab President, John Bogler, was working as an engineer at Shimano when the company introduced the linear-pull brake (AKA v-brake) to the market in the early 90s. The linear-pull brake has since become the most common type of bicycle brake used on bikes today and is the system SURESTOP integrates with. Upon seeing SURESTOP for the first time, John was impressed with the solution to a common problem he in an expert in – bicycle pitch over. In 2010, John co-authored a paper called “Analysis of Bicycle Pitch-Over in a Controlled Environment”, helping him understand the physics of head-over-handlebar accidents. Despite being intrigued by the solution, John and his team were eager to test all the claims of our technology.

ACT Lab Testing of SURESTOP

In 2013, ACT Lab began testing SURESTOP for a few bicycle brands looking to use the technology on their bikes.

Durability testing – tests were run for 1000 miles and 5000+ brake actuations, which historic labratory testing has shown to represent the average quality life span of a comfort bicycle. The SURESTOP did not show any signs of failure during this test.

Marketing Claims – tests were done to see if the SURESTOP brake system would not lock up the front wheel in both wet and dry braking, and to see the stopping distance of the SURESTOP system vs traditionary two lever systems. Harm Jansen, former professional bike rider and bicycle accident reconstructionist at Collision and Injury Dynamics, was chosen as the test rider to conduct these tests. See video below of Harm Jansen after testing SURESTOP.

About Element (formerly Stork Techniment)

Element Materials Technology exists to ensure that the materials and products that are in use in some of the world’s most advanced industrial sectors are always safe; of marketable quality; compliant to all relevant industry standards and most of all are fit for purpose in their end application. What we ultimately deliver is Certainty to those industries where failure simply is not an option. That is “The Certainty of Element”

Stork Techniment SURESTOP Testing

Objective – to evaluate the braking system and determine if it met the braking distance requirements of CPSC 16 CFR part 1512, and to compare the braking performance to a traditional two lever system.

Results

Both the traditional and the Slidepad braking systems are able to meet the performance requirements of CPSC 16 CFR part 1512 for braking distance.

In general the traditional braking system stopped faster than the Slidepad system when both levers were engaged by knowledgeable and experience riders Rob Evans and Chris Monson.

In these tests the Slidepad braking system performed about the same for wet and dry conditions,

In these tests, the front wheel of the Slidepad system never locked up. No attempt was made to lock up the front wheel of the traditional system for safety reasons.
